I'm trying out Google Keep for iOS 9 on an iPhone 5. I've given the app permission to produce banners, sounds and alerts in the Notification Center. Timed reminders from Google Keep do show as banners, but no sound or vibration is produced. For me, alerts without sound or vibration are easy to miss. The silence switch is OFF for this phone (sound is on).
Has anyone found a combination of settings, or some strategy to cause sound and/or vibration with banners raised by Google Keep for iOS?
Any help is much appreciated. Thanks!
